IMPROVEIVlENT IN DRINKING-GLASSES.

Specification forming part of Letters Patent No. 195,337, dated September 18, 1877 application filed May 22, 1877.

To all whom it may concern:

Be it known that I, CHARLES B. BRAUNSTEIN, of Cincinnati, Hamilton county, State of Ohio, have invented an Improvement in Drinking- Glasses, of which the following is a specification:

My invention is designed to add to the durability of delicately-constructed drinking glasses.

It consists of a goblet embracing the fol- A glass bowl or cup, with a plain central perforation in a thickened bottom; a metallic pedestal, consisting of a slender stem, having a screw-threaded socket at the upper end and a broad base; a headed screw, to enter the socket in the stem from the interior of the bowl, and a gasket to make a joint, the whole constituting a drinking-glass elegant in form, light in weight, fascinating and fragile in appearance, and yet possessing great strength of stem, and ofiering facilities for convenient substitution of a new bowl or cup for a broken one.

The accompanying drawing is an elevation, partly in section, of my new drinking-glass.

A is the bowl or cup. It is usually made of very thin glass, and when so made I make the central portion, as shown at a, thicker than the body of the bowl, so as to stand the strain of the fastening. If the bowl is of thick glass the thickening at the bottom is, of course, unnecessary.

B is the pedestal. It is composed of stem b and base-plate b, all of metal, and preferably in one piece, of white metal, plated.

A screw-threaded socket, b, is formed in the top of the stem to receive the connectingscrew 0. The shank of this screw extends through a plain aperture in the glass into the socket and has a hemispherical head, between which and the bottom of the glass I interpose a gasket, D, of vulcanized fiber or other suitable material.

The parts are put together by first placing the gasket on the screw, and then placing the screw through the aperture in the glass and holding it firmly with the thumb or finger, and then, while so holding the screw, screwing on the pedestal.

I am aware that the bowl and stem of goblets, &c., have heretofore been made of separate pieces, one being provided with a screwthreaded socket, and the other with a screwthreaded shank, as means for uniting them. I do not therefore claim, broadly, drinkingglasses in which the bowl and stem are separable, but confine myself to the special means of connecting the parts.

I claim A drinking-glass having bowl A a, pedestal B b b b, detachable-headed screw C, and gasket D, substantially as and for the purpose specified.

In testimony of which invention I hereunto set my hand.

CHARLES B. BRAUNSTEIN.
